시내버스 준공영제 시행은 시내버스 운전자의 신분안정과 근무환경, 복지의 향상을 가져왔다. 이러한 혜택은 시내버스 운전자의 이직을 방지하여 시내버스 운전자들의 연령이 증가하고 있다. 시내버스 준공영제 시행 후 시내버스 교통사고 중 사망사고가 증가하는 등의 부작용이 사회적 문제로 부각되고 있다. 이러한 시내버스 준공영제로 인한 문제점을 최소화하기 위하여 시내버스 교통사고의 저감대책 마련 시 운전자의 연령 증가와 이로 인한 고령운전자의 운전행동 특성을 반영한 교통사고 저감대책 마련의 필요성이 최근 부각되고 있다. 기존의 고령운전자의 교통사고저감 대책 마련은 단순한 정책방향이 대부분이었다. 이러한 한계를 극복하기 위하여 본 연구에서는 실제교통사고 야기자인 고령운전자와 비고령운전자를 대상으로 설문조사와 함께 운전정밀적성검사를 통하여 운전행동특성을 파악하였다. 그 결과 고령운전자의 운전행동특성을 정확하게 알 수 있었다. 또한, 구조방정식을 통한 고령운전자 행동 특성 분석모형 결과를 통해 고령운전자의 교통사고 저감대책을 마련, 제시 할 수 있었다.

전라북도내 14개 시 군의 교통사고 자료를 활용하여 고령운전자의 교통사고 피해 심각성을 분석하였다. 교통사고는 1차적으로 개인 및 운전환경 속성과 2차적으로 도시관련 속성에 의해 영향을 받는 2단계 위계적 특성을 갖는 것으로 가정하였다. 위계적 특성을 고려한 피해 심각성에 대한 영향요인을 분석하기 위해 다수준분석모형을 활용하였다. 분석결과로서 65세 이후의 고령운전자는 연령이 증가할수록 교통사고로 인한 피해상황이 심각해짐을 보여주며 안전한 운전방법의 교육과 교통사고를 미연에 방지하기 위한 대안이 필요하다. 음주운전은 고령운전자에게 사고발생시 피해 심각성을 크게 할 경향이 높은데, 사망사고에 있어서 비고령자에 비해 발생비율이 약 3.0배 이상 높았다. 고령운전자는 야간 교통사고 발생빈도가 높은 편이나, 낮 시간대의 교통사고일수록 피해 심각성은 높아졌다. 고령운전자는 비고령자보다 흐린 날씨에서 사고 발생빈도가 높으나, 심각성에서는 맑은 날에 높아짐을 보였다. 습윤상태의 노면이 피해 심각성에 큰 영향을 주고 있는데, 비고령자에 비해서 고령운전자가 중상 및 사망비율도 높은 것으로 분석되었다.

Due to the ageing-related degradation in physical and cognitive abilities, the elderly have difficulty in car driving and this is related to the high rate of car accidents among them. This study investigated the kinematic characteristics of old drivers' steering in right turning at intersections by comparing with young drivers. Thirteen old(60~70) and thirteen young(20~30) drivers who participated in the experiment turned their cars right side at intersections in a driving simulator. As results, the completion time of right turning at intersection of old drivers was larger than that of young drivers. The speeds of vehicle at the beginning and ending point of the right turning area of old drivers were smaller than those of young drivers, and also the steering angle at the ending point of the turning area of the former was smaller than that of the latter. The normalized jerk of old driver's steering was significantly larger than that of young drivers. These results indicate that old drivers modify their steering movement repeatedly and take the driving strategy of avoiding risks due to their reduced physical capabilities.

The aging of society is not only Korea's challenge but also a global issue. This leads to an increase in the number of elderly drivers who are much more prone to major traffic accidents. Therefore, we need a system to test aged drivers' driving abilities. As part of efforts to establish such a system, researchers of KoROAD. have conducted a study on the correlation between aging and driving abilities by analyzing old drivers' reaction time. The study shows that there was a sharp increase in reaction time for drivers aged 65 and over. The current reaction time of 2.5 secs for the 85 percent of eligible drivers needs to be revised upward in aging societies. From now on, we need to come up with the traffic safety measures that can deal with the issue of drivers of old age.

Purpose: For prevention and suitable administration, the effect of age on the severity of injuries in traffic accidents should be considered when evaluating a patient, but there have not been enough epidemiological studies that evaluate the age factor in traffic accidents. For that reason, we investigated old-aged patients who were involved in traffic accidents (65 years old or more) and who were admitted to the emergency department of a college hospital in an urban city of Korea. Methods: We collected data from traffic-accident patients who came to the emergency room of a university hospital in Seoul from Jan.1, 2004 to Dec.31, 2005. We compared their abilities to ambulate and the RTSs (Revised trauma scores) by using a LSD (least significant difference), linear regression. Results: A total of 1460 patients were included. The mean RTS of all traffic-accident patients was $7.77{\pm}0.280$. The scores for drivers and passengers, motor-cycle drivers and passengers, bicycle drivers and passengers, and pedestrians were $7.79{\pm}0.21$, $7.78{\pm}0.22$, $7.54{\pm}0.25$, $7.77{\pm}0.20$, and $7.80{\pm}0.21$ respectively (p=0.000). There was no statistically significant difference between the RTS of patients over 65 years and that of other patients. In a regression analysis, the number of patients over 45 ages who were able to ambulate was lower than that of younger people, independently of other influencing factors (B=-0.330, R-square = 0.243, p=0.000). Conclusion: We expected that RTS of old age group more than 65 years old will significantly lower than that of others, but there was no statistically significant difference.

주요국에서는 증가하는 노인운전자의 교통사고 경감을 위해 연령별 자동차 사고 위험도를 분석한 후, 위험도가 높은 고령자의 교통사고를 경감하기 위한 다양한 제도를 시행하고 있다. 최근 우리나라 교통사고는 감소하고 있지만 65세 노인운전자의 교통사고는 빠르게 증가하고 있음에도 불구하고 노인운전자의 자동차사고 위험도에 대한 실증연구가 부재하고, 관련제도 개선이 이루어지지 않고 있는 실정이다. 이에 본 연구에서는 우리나라 운전자들의 연령별 자동차사고 위험도를 분석하였는데, 25세 미만 연령층을 제외하고 65세 이상 노인운전자의 자동차사고 위험도가 가장 높은 것으로 분석되어졌다. 세계에서 가장 빠른 인구고령화를 경험하고 있는 우리나라에서도 주요국처럼 노인운전자에 대한 운전교육 및 운전면허 재발급 자격을 강화할 필요가 있겠다. 또한 노인운전자를 배려한 도로표지판 개선과 노인운전차량 스티커 부여, 그리고 자가운전 대신 대중교통을 운전하는 노인들에 대해 인센티브를 제공하는 유인체계의 변화가 필요하다.

The weight of elderly people in Korea has been increasing. Statistics show that the percentage of the elderly people in Korea was 3.1% in 1970; 3.8% in 1980; 5.1% in 1990, and 7.2% in 2000. Based on this trend, thus, the number of elderly people could be estimated to be 14% of the whole Korean population in 2018. This reveals that Korea is entering a super-aging society with remarkable fast pace. In such a change, the statistics related to elderly people driving license and the occurrence of traffic accidents are showing a noticeable numerical value. The number of traffic accident fatality in Korea ranks the highest value in OECD Countries. However, the research on old drivers in the nation is going on partially centering on system improvement and management scheme. Thus, first of all, researches about the linkage & characteristics between the driving behavior of old drivers and traffic accident should be implemented, in order properly to draw system improvement and management scheme for the old drivers. Therefore, the focus of this study is the influence model for discerning the severity of the age-old-caused traffic accidents by inquiring into the relation between the Driving Aptitude Test items that make it possible to measure their behavioral characteristics and influential factors by age group on the basis of the data on traffic accidents. The analysis results can be used as basic data for suggesting the behavioral research and countermeasure for traffic safety and its management for old driver in preparation for the aging society.

Assuming the majority of car accidents are due to driver errors, we due rear-end collisions which occurred in the State of Washington, USA, in 1982, 1983, and 1984, to study human responsible involvement associated with the sex and age of drivers. Rear-end collisions involving two passenger cars are included in this study. The driver of a car which struck the rear end of another car is considered responsible for the accident, and the driver of a car which was struck in the rear end is not considered responsible for the accident. In addition to male and female drivers, we used three different age groups: 16 to 24 years old, 25 to 34 years old, and 35 years or older. Hence, six diferent groups of drivers are considered in this study.

PURPOSES : This study deals with first traffic violations occurred by novice drivers, which may be associated with traffic accidents. The objective of this study is to identify what kinds of drivers' characteristics influence on duration till the first traffic violation. METHODS : For the study, Survival Analysis and Cox proportional hazard model, that are usually used in the medical field, were employed. Survival Analysis was conducted to investigate whether there exist differences in survival duration by each covariate, whereas Cox proportional hazard model was used to identify significant factors that affect survival duration till novice drivers violate traffic regulations for the first time after getting a driver license. RESULTS : The results of Survival Analysis indicate that female, age (less than 21), low-frequency examinee of written exam, and non-crash involved drivers have longer duration till the first violation compared to male, greater than 21 years old, high-frequency examinee of written exam, and crash involved drivers, respectively. For the Cox proportional hazard model, license class 1 acquisitor was found to increase the survival duration till the first traffic violation was made, while male, age of 21-24, age of 25-34, age of 45-54, and crash involved drivers were more likely to reduce the survival duration. CONCLUSIONS : Absolutely, traffic violation is closely related to traffic accidents and all of the drivers should keep the traffic regulations to enhance highway safety. The results of this study might provide some insights to construct safe road environments by controlling the factors that reduce the traffic violation duration of novice drivers.

The traffic accidents of the aged are increasing because old people generally experience a decline of physical functions and judgment but their dependence on automobiles increases. In order to investigate the older drivers' response to traffic signs and surrounding environment according to changing driving brightness, this study measured the visual cognitive behavior, driving behavior, and subjective evaluation while the driving brightness was changed using a driving simulator. Furthermore, the drivers who recognized traffic signs and those who did not were compared. As a result, it was found that some older drivers had declined ability of cognition, some failed to adapt to rapid brightness change even if sufficient attention was given to traffic sign, and some could not safely control the vehicle when approaching intersections. Therefore, the development of support systems for aged drivers in traffic environment is necessary in the future.
